Workaround

Users should carefully use HTTP if necessary, and could try to replace HTTP by HTTPS when using the web service. Additionally, refer to the following mitigation measures to deploy the product in an appropriate product security context. Moxa recommends users follow CISA recommendations.   * Reduce network exposure by ensuring that all control system devices and systems are not accessible from the Internet. * Place control system networks and remote devices behind firewalls, isolating them from business networks. * When remote access is necessary, employ secure methods such as Virtual Private Networks (VPNs). It is important to note that VPNs may have vulnerabilities and should be kept up to date with the latest available version. Remember that the security of a VPN depends on the security of its connected devices.
